  • OPTICAL ELEMENT FOR STABILIZING REFRACTIVE INDEX PROFILES USING POLYMER MIXTURES
    Publication number: 20100302504
    Abstract: An optical element comprising: a first monomer polymerized while in the presence of a second monomer to form a first polymer intermixed with the second monomer, the first polymer having a spatially varying degree of cure that provides a predetermined refractive index profile; and the second monomer polymerized in the presence of the first polymer to form a second polymer intermixed with the first polymer, the second polymer stabilizing the refractive index profile.
    Type: Application
    Filed: August 10, 2010
    Publication date: December 2, 2010
    Applicant: Ophthonix, Inc.
    Inventors: Shui T. LAI, Donald G. Bruns, Lawrence H. Sverdrup, Gomaa G. Abdel-Sadek
